Description
Technical field:
The invention belongs to technical field of buildings, refer in particular to a kind of structural floor that utilizes as the construction method of the structural system of horizontal support.
Background technology:
Along with the fast development of urban construction, the problems such as urban land resource is nervous, congested in traffic become increasingly conspicuous, and the development of the underground space becomes inexorable trend.Thereupon; contradiction between underground space development and environmental protection progressively manifests; for solving this contradiction; people set about research Base hole supporting technology and Construction Techniques for Deep Foundation Pit, and along with excavation of foundation pit is more and more darker, area is increasing, design and the construction of foundation pit enclosure structure become increasingly complex; for reducing foundation pit deformation to the impact of surrounding enviroment; the number of plies of inner support also gets more and more, and the ratio that base pit engineering accounts for project total cost is increasing, and resource consumption is larger.Therefore the integrated conduct method that combines with construction method of a kind of space enclosing structure of necessary exploration.
Foundation Design is the most frequently used construction method of excavation of foundation pit along practice construction, and most base pit engineering is all adopt along way construction.It has, and construction is simple, cost is low, and speed is fast, be convenient to the advantages such as big machinery operation.But be reinforced concrete inner support system or bracing members all exists some problems, bracing members construction precision requires higher, by component processing, man's activity degree is larger, careless slightly with the node processing going along with sb. to guard him junction, foundation pit enclosure structure can be caused to produce moderate finite deformation, affect the use of foundation ditch, severe patient affects the construction of Foundation Design; Although reinforced concrete support inner support rigidity is larger, space enclosing structure distortion effectively can be controlled in the excavation stage, but need support replacement in the structure construction stage, in support replacement process, space enclosing structure is a kind of new force status, and reinforced concrete inner support needs to cut, affect surrounding environment and waste resource.
Foundation Design reverse construction mainly applies to that foundation ditch is comparatively dark, surrounding environment is complicated, go along with sb. to guard him Deformation control requires higher engineering, namely first construction is gone along with sb. to guard him and central pile, post construction, by certain supplementary means (as increased bracing members etc. in position by calculating), be excavated to absolute altitude at the bottom of every layer of beam slab successively from top to bottom subsequently, to construct this Rotating fields floor, using the inner support of this Rotating fields floor as space enclosing structure.
Summary of the invention:
The object of this invention is to provide a kind of safety increasing foundation ditch, reduce surrounding enviroment impact, what ensure that the construction of base pit engineering carries out smoothly utilizes structural floor as the construction method of the structural system of horizontal support.
The present invention is achieved in that
Utilize structural floor as a construction method for the structural system of horizontal support, concrete steps are as follows:
(1) construct in foundation ditch space enclosing structure, Reinforcement with Cement-mixed Piles foundation soil and engineering pile foundation and support pile foundation;
(2) constructing structure post on engineering pile foundation, Construction Support post in support pile foundation, installs in the first steel lattice column, support column and arranges the second steel lattice column in structural column;
(3) cut the earth from top to bottom according to Foundation Design contrary sequence method, while cutting the earth, corresponding cement mixing pile is excavated, dig the bottom to first reinforced concrete inner support, then construction first reinforced concrete inner support and first enclose purlin simultaneously, described enclosing on purlin is reserved with pouring hole and steel bushing, pouring hole is used for pouring structure side wall, and steel bushing connects the vertical reinforcement of corresponding structure side wall;
(4) continue to cut the earth downwards, according to design needs, if need to arrange temporary support, then dig the bottom to first bracing members, then construction first bracing members, if do not need to arrange bracing members, directly carries out next step construction, i.e. step (5);
(5) continue to cut the earth downwards, dig the bottom to B1 structural floor, then construction second concrete inner support, B1 structural floor and second enclose purlin simultaneously, described enclosing on purlin is reserved with pouring hole and steel bushing, pouring hole is used for pouring structure side wall, steel bushing connects the vertical reinforcement of corresponding structure side wall, and B1 structural floor is reserved with unearthed hole;
(6) repeat step (4), (5) continuation is cut the earth downwards, according to design needs, if need to arrange temporary support, then first repeat step (4), corresponding bracing members is installed, continue again to cut the earth downwards and repeat step (5) and to construct corresponding concrete inner support, structural floor and enclose purlin simultaneously, described enclosing on purlin is reserved with pouring hole and steel bushing, pouring hole is used for pouring structure side wall, steel bushing connects the vertical reinforcement of corresponding structure side wall, and each structural floor is reserved with unearthed hole;
If do not need to arrange temporary support, then directly repeat step (5) to construct corresponding concrete inner support, structural floor and enclose purlin simultaneously, described enclosing on purlin is reserved with pouring hole and steel bushing, pouring hole is used for pouring structure side wall, steel bushing connects the vertical reinforcement of corresponding structure side wall, and each structural floor is reserved with unearthed hole;
(7) cut the earth to sole plate, construction cushion coat, cushion cap and base plate;
(8) include temporary support in above-mentioned steps, then first remove temporary support, if do not comprise temporary support, directly carry out next step construction;
(9) to construct successively from the bottom up each Rotating fields side wall along the practice according to Foundation Design;
(10) unearthed hole reserved in each structural floor of constructing;
(11) beam and slab structure at construction top.
Above-mentioned reinforced concrete inner support is all reserved with sleeve, and sleeve is for connecting reinforcing bar when building reserved unearthed hole place structural floor.
